Definitions

  • the present invention relates to a sealing device and a wound closure device according to the preamble of claims 1, 6 and 7, respectively.
  • an introducer is used to access the vascular system of a patient.
  • the introducer is inserted through the wall of a blood vessel in order to obtain access to the vascular system and may thereafter be used for guiding medical instruments such as catheters, guide wires and the like.
  • medical instruments such as catheters, guide wires and the like.
  • After the completion of the medical procedure there will be an incision or a wound in the wall of the blood vessel corresponding to the size of the introducer.
  • the bleeding from the wound which is the result of such a surgical operation, may be stopped by applying direct pressure on the wound.
  • applying direct pressure on the wound will require assistance of medical personnel and may also restrict the blood flow through the vessel.
  • US 5,342,393 describes a sealing device for sealing a perforation in the wall of a blood vessel.
  • the device is in the form a two-part rivet, which seals the hole from both the inside and the outside of the vessel.
  • Two rivet portions, an outer rivet portion and an inner rivet portion, are provided which are bayonet or screw threadedly interlocked to clamp the vessel wall.
  • a problem with such a sealing device is that when screwing the outer rivet portion also the inner rivet portion will rotate since there is no holding-up on the inner rivet portion from the inside of the vessel, and thus it is hard to know if the sealing device is properly sealed or not. The latter may have disastrous consequences with blood leaking vessels.
  • US 5,342,393 is also shown a sealing device, locked together via interlocking ridges.
  • the inner rivet stem has triangular ridges that define horizontal shoulders and the outer rivet may have one or more upside down triangular ridges that define an opposing shoulder for engaging an adjacent shoulder and to thereby allow the outer rivet to be slid over the inner rivet but prevent separating movement.
  • both the inner rivet stem and the outer rivet HAVE so-called saw teeth.
  • a problem with this sealing device is that the distance between the two occluders (i.e. rivets) may be varied only between fixed positions and thus cannot be exactly adapted to the thickness of the vessel. This in turn can lead to deteriorated tightening of the vessel if the distance exceeds the thickness of the vessel. On the other hand, it can also lead to the vessel being clamped with undue pressure on the vessel, which in turn might result in tissue necrosis or rupture of the arterial wall, when the distance is less than the thickness of the vessel.
  • the sealing device is constructed of a first member in the form of an intra-arterial occluder comprising a guide means in the form of an elongated wire integral with and extending centrally from the intra-arterial occluder and a second member in the form of an extra-arterial occluder.
  • the guide includes a portion extending from the intra-arterial occluder which contains a plurality of saw teeth while the extra-arterial occluder is provided with an opening through which the guide passes.
  • the saw teeth are wider in diameter than the opening in the extra-arterial occluder so that the extra-arterial occluder can be passed over the teeth in a direction towards the intra-arterial occluder.
  • a sealing device commonly is inserted via an elongated introducer extending not perpendicular to the blood vessel, but in an acute angle towards the vessel, to get a insertion direction which is as close to the direction of the vessel as possible.
  • This problem concerns the difficulty of bringing the two occluders close enough to each other so as to tighten the vessel, because if the occluders cannot be adapted to the vessel wall, the vessel wall has to be deformed to fit towards the occluders which requires an increased sealing force between the occluders.
  • the angle also causes tensions to the elastic vessel wall since the vessel wall that is in contact with the sealing device becomes parallel to the surface of the occluders which makes the incision of the vessel wall dilated and the tightening more difficult.
  • the inventors found that these two problems do not arise at all when said sealing device surfaces are parallel to said vessel surface in the sealing moment, but the problem increases the larger the angle becomes.
  • the stem closest to the inner rivet will be perpendicular to the inner rivet surface and the surface of the vessel, but be bent and making an arc, towards the acute angle of the elongated introducer where it thus is perpendicular to the surface of the outer rivet which is to be in contact with the surface of the vessel.
  • the distance between the saw teeth on the stem will then be different on the outside and the inside of said arc, making it problematic to get a good engagement between the saw teeth on the stem and the outer rivet.
  • the objective problem to be solved by the present invention is to provide a sealing device for closing a wound, which has enhanced tightening properties.
  • the sealing device Since the elongated member constitutes or is coated by a suture wire, and has a constant thickness along its lock portion, the thickness being greater than the opening of the second sealing member, the sealing device is infinitely variable lockable along the distal lock portion.
  • the present invention provides a novel and easy-to-use sealing and wound closure device for closing a wound with excellent sealing properties.
  • Figure 1 shows a sealing device for closing a wound in a wall of a vessel according to a first embodiment of the invention.
  • Figure 2 shows a sectional view of a first sealing member.

  • Figure 16 shows a sealing device for closing a wound in a wall of a vessel according to a fifth embodiment of the invention.
  • Figure 17 shows a sealing device for closing a wound in a wall of a vessel according to a sixth embodiment of the invention.
  • Figure 18 shows a cross sectional view of the first sealing member compressed inside the introducer according to Figure 8, seen along the line A-A.
  • Figure 1 shows a sealing device for closing a wound in a wall of a vessel according to a first embodiment of the invention.
  • the sealing device comprises three separate parts, namely a first sealing member 2, an elongated member 4 and a second sealing member 6.
  • the first sealing member 2 is attached to a distal end of the elongate member 4.
  • the first sealing member comprises two through openings 8, 10 ( Figure 2 ) through which a multifilament suture wire 12 is thread so as to make a pair of suture wires constituting the elongated member 4.
  • the second sealing member 6 is provided with an opening 14 ( Figure 3 ), which is adapted to the elongate member 4, i.e. the opening 14 is greater than the thickness of the proximal portion of the elongate member 4. With a structure like this the second sealing member 6 is threadable onto and along the elongate element 4 ( Figure 1 ). The most distal portion of the elongate member 4 has a constant thickness that is slightly greater than the opening 14 of the second sealing member 6 and constitutes the distal lock portion 16.
  • the multifilament suture wire 12 is preferably made of a resorbable material such as Glycolic/Lactide polymer.
  • the first sealing member 2 and second sealing member 6 are preferably made of a flexible resorbable material, such as Caprolactone/Trimethylene Carbonate/Glycolide polymer or any corresponding materials.
  • a suture wire for the elongated element 4 is very important for the safe securing of the sealing device. Tests have been made to use the same material, e.g. a polymer, in the elongated member 4 as in the second sealing member 6. Since polymer gives a very glossy surface, it is hard to get high power frictional engagement between the elongated member 4 and the sealing member 6. Using a suture wire 12 for the elongate member 4 gives a safer sealing since the suture wire comprises a number of circulating fibres thus giving the wire a rough surface with a high frictional sealing power towards a glossy surface inside the opening 14 of the second sealing member 6. The suture wire also makes the sealing device safer in another way.
  • a suture wire 12 for the elongate member 4 gives a safer sealing since the suture wire comprises a number of circulating fibres thus giving the wire a rough surface with a high frictional sealing power towards a glossy surface inside the opening 14 of the second sealing member 6. The suture wire also makes the sealing device safer in another
  • the suture wire is made in one piece and has very high tensile strength. It constitutes a continuous wire from the inner seal through the outer seal and to a tampering grip of the insertion tool, being threaded in through the first opening 8 and out again through the second opening 10 and thus keeping the sealing device safe together. If a first sealing member and an elongated member are cast in one piece there is often problems with the casting process, giving the casted member air bubbles and inclusions and accordingly giving the sealing device poor structural strength. The challenge is to make the suture wire 12 thicker in the distal lock portion 16.
  • a hollow core of the suture wire 12 is filled with an elongated core 18 ( Figure 5 ), within the area of the distal lock portion 16 of the elongate member 4, but also in the area which is to be threaded through the first sealing member 2. (See again Figure 1 ).
  • the elongated core 18 is preferably made of a resorbable Caprolactone/Trimethylene carbonate/Glycolide polymer. This gives the suture wire 12 a thickening in the distal lock portion 16.
  • the suture wire 12 is left unfilled within the area ranging from the entry of the first opening 8 of the first sealing member 2, through the first sealing member 2, out on the other side and in again through the second opening 10 of the first sealing member 2 to the exit of said second opening 10.
  • the thickening of the first suture, of the two sutures making a pair of sutures extends beyond the distal lock portion 16 into the proximal portion of the elongated member 4. This gives the suture wire 12 a more continuous increasing of the thickness which simplifies the threadening of the second sealing member 6 from the proximal portion onto the distal lock portion 16.
  • the suture 12 is thicker woven in the area of the distal lock portion.
  • the second sealing member is divided into two parts, which first part 41 is a plate and is provided with an opening that is approximately the same or slightly greater than the thickness of the distal lock portion 16.
  • This first part 41 is threadable onto and along the elongate member 4 ( Figure 15 ), over the distal lock portion until it is in contact with the outside of the vessel wall.
  • the first part plate 41 is preferably quite thin, which makes it flexible and easy to adapt to the vessel wall.
  • the second part 42 is provided with an opening that is slightly smaller than the thickness of the distal lock portion 16. This second part 42 is threadable onto and along the elongate member 4 ( Figure 15 ), over the distal lock portion until it is in contact with the first part 41.
  • the second part 42 allows for frictional engagement between the inside of the opening of the second part 42 and the distal portion 16 ( Figure 16 ).
  • the second part 42 is preferably thicker than the first part 41, which gives it a large surface inside its opening for said frictional engagement.
  • the diameter of the second part 42 is preferably smaller than the first part 41.
  • the elongated portion 4 is not a suture wire, but another material, e.g. a resorbable polymer ( Figure 17 ).
  • the distal lock portion 16 is coated by a hollow suture wire like a stocking so that a decent frictional engagement can be achieved between said coated distal lock portion and the inside of the opening of the second sealing member.
  • Typical dimensions of parts of the sealing device are for the first and second openings 8 and 10 of the first sealing member 2, a diameter of 0.2 mm, and for the opening 14 of the second sealing member 6, a diameter of 0.5 mm.
  • the typical dimension of the suture is a diameter of 0.25 mm and of the distal lock portion 16, a diameter of 0.4 mm and a length of is 8 mm.
  • Figure 2 and Figure 3 show respectively a sectional view of an example of a first sealing member 2 and a second sealing member 6 according to the embodiments of the invention.
  • the first and second sealing member 2, 6 will pass through an introducer 24 (see Figure 8 ) on the way to its final position in the wound. Since the first and second sealing member 2, 6, each has a diameter that is greater than the diameter of the introducer 24, they are made compressible.
  • the first and second sealing member 2 and 6, according to the present invention are preferably built up of portions that are foldable and portions that are more rigid, but other shapes are also possible.
  • Figure 18 shows a cross sectional view of the first sealing member 2 compressed inside the introducer 24 according to Figure 8, seen along the line A-A.
  • Figure 8 shows a wound closer device, which comprises the sealing device of any of the embodiments, mentioned above and a pusher 22 adapted for pushing the first sealing member 2, the elongated member 4 and the second sealing member 6 through an introducer 24.
  • the sealing device will be passed through the introducer 24 in order to reach its final position in the wound to be closed.
  • the pusher 22 may be used to push the first sealing member 2, the elongated member 4 and the second sealing member 6 through the introducer 24.
  • the pusher 22 has a size adapted to the size of the introducer 24, i.e. the diameter of pusher 22 is smaller than the inner diameter of the introducer 24 such that the elements of the sealing device can be pushed through the introducer 24.
  • the pusher 22 is provided with a through hole 26 along the longitudinal axis thereof. This through hole 26 is large enough to accommodate the elongate member 4.
  • Figure 9 shows a sectional view of a wound site, with an introducer 24 extending through the vessel wall 28 and into the vessel 30.
  • the introducer 24 is introduced through the skin and passes the tissue 34 before it penetrates the vessel wall 28 and enters the vessel 30.
  • a wound will be left in the vessel wall 28. It is that wound that the wound closer device according to the present invention will close, with use of the wound closure device and sealing device described above.
  • Figure 10 shows a sectional view of the wound site, with the pusher 22, the first sealing member 2, the elongated member 4 and the second sealing member 6, inside of the introducer 24.
  • the first sealing member 2 has been pushed such that it is situated in the distal end of the introducer 24.
  • the first sealing member 2 is in a compressed state.
  • the pusher 22 is pushed until a first sealing (not shown) of the pusher 22 abuts the proximal end of the introducer 24 and the first sealing member 2 has reached the state shown in Figure 11.
  • the first sealing member 2 extends outside of the introducer 24 and into the vessel 30.
  • the first sealing member 2 is outside of the introducer 24 it will unfold to an expanded state.
  • Figure 12 shows the next state, wherein the introducer 24 is drawn out of the vessel 30 until it reaches the tissue outside of the vessel wall 28.
  • the second sealing member 6 is pushed outside the introducer 24.
  • the second sealing member 6 is threadable onto and along the elongated member 4, it is possible to adapt the sealing device to wounds having different thickness.
  • One of the great advantages with the sealing device of the present invention is that it is adaptable to the thickness of the wound or vessel wall 28.
